ICAF Compliance and Release Option Selection

ICAF is an FM approved Integrated Compressed Air Foam System designed under NFPA 11 with related NFPA 13, NFPA 24, NFPA 72, local code, and AHJ requirements. The release option should match the hazard, detection strategy, and operational needs.

Yes. FireFlex ICAF documentation states design and installation are covered by NFPA 11 and that the system is FM approved when installed with specific components.

What the compliance basis includes

FireFlex documentation references:

  • NFPA 11
  • NFPA 13
  • NFPA 72
  • NFPA 24
  • applicable local and state building codes
  • additional AHJ requirements
What each release option means
Manual release

Choose when the application depends on trained personnel to initiate discharge and automatic release is not the design intent.

Pneumatic release

Choose when pneumatic actuation is preferred as part of the control philosophy or hazard approach.

Electric release

Choose when the system will be integrated with automatic fire detection and releasing controls.

Electric fail-safe release

Choose when the project wants an electric release approach with added fail-safe behavior as defined by the manufacturer’s design basis.

When to choose ICAF

Choose ICAF when:

  • the hazard is better protected by compressed air foam than by sprinkler-only protection,
  • FM approval is required for the foam system approach,
  • the project team is prepared to design within manufacturer approval limitations,
  • nozzle spacing, water supply, and discharge duration can be designed within the approved envelope.
Critical compliance note

FireFlex documentation warns that unauthorized field modification of a factory-built approved system can void the FM approval. That is especially important for AHJs, contractors, and owners planning field changes.

Frequently Asked Questions

Is ICAF designed only to one NFPA standard?
No. NFPA 11 is the main foam basis, but related installation and alarm standards also apply.

Can ICAF be used without reviewing approval limitations?
No. Nozzle spacing, coverage, pressure, duration, and components must stay within the FM approval and design manual limits.

Does the AHJ still have authority if the system is FM approved?
Yes. The AHJ still reviews code compliance and the specific installation.
